When an international conglomerate unleashes a virus on the world, most people are turned into flesh-eating zombies and the earth into a desert, leaving a band of survivors, led by two men (Oded Fehr and Mike Epps) and two women (Ali Larter and Ashanti), to form a convoy in search of other uninfected people, their travels at length bringing them into contact with a superwoman (Milla Jovovich) who is out to fight the evil doctor (Iain Glen) who experimented on her and who still hopes to turn the virus to the corporation's advantage. Watching director Russell Mulcahy's gorefest may be the cinematic equivalent of combat: moments of jarring fear are interspersed with long periods of abject tedium. Nearly constant blood, gore and mutilation, cannibalism, brief frontal and upper female nudity, drug use, and much crude and some crass language.
